"...runs it through a BRIDGE RECTIFIER!"

Is that bad? If you're turning AC into DC you're gonna have to rectify it somehow.

    I know his entire shtick is doing dumb stuff and getting hurt (or at least pretending to?) in the style of "Ow! My balls!", but he wouldn't have been able to touch across 170VDC without flinching (@ 1:55). I've felt ~48VDC in the summer with my hands a bit sweaty. And both those terminals were actually still bouncing between +/- 170V along with the AC supply. Then at 3:55 he gets shocked from touching those same terminals (as he should), with the circuit disconnected from the AC line, to segue into the need to discharge capacitors. This is what makes me question how much of his "getting hurt" is actually acting. (Also just in case anyone is watching those videos and thinks there's a distinction between his usual haphazard behavior and when he gives explicit "safety" advice - there isn't).

      That 'hands a bit sweaty' affects the outcome way more than you'd think. I've had a seriously unpleasant nip from a mere 24VDC (while drenched in sweat) and only a mild tingle from 90VDC (in an air conditioned office). In this case I'd guess he's got some decent calluses and any leakage current isn't going through any nerves. Also he's only touching it lightly so won't be making very good contact.

  I believe the parent was referring to the "full bridge rectifier" joke by a popular electronics content creator: https://electroboom.fandom.com/wiki/Full_Bridge_Rectifier https://electroboom.fandom.com/wiki/Full_Bridge_Rectifier.

    Ohhhhh damn I've watched a bunch of his stuff in the past but not run across this particular one. He's great.

Should have added a little clip of him to the video...
